Electricity and Magnetism Study Guide

Front

What is electricity?

Back

Electricity is the flow of electric charge, typically carried by electrons, which can be used to power devices and perform work.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is a conductor?

Back

A conductor is a material that allows electric current to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current, such as rubber or glass.

Front

What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, typically associated with magnets and magnetic fields.

Front

What is a magnetic field?

Back

A magnetic field is the area around a magnet where magnetic forces can be detected, strongest at the poles.

Front

What is an electric motor?

Back

An electric motor is a device that converts electrical energy into mechanical energy to perform work.

Front

What happens to a magnet when electric current is lost?

Back

The magnetism of the object, such as a screw, will disappear, and it will no longer be magnetic.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points.
